Thank you! Glad to hear the content has been helpful. More coming every week.

I have read up about this on & off over the years whenever it caught my interest back again or my interest got re-ignited, this also includes clips. I say that to say This Video is hands down the most informative & well researched I have seen yet about this issue! I appreciate all the terminology & concepts, Vapour throttle makes a lot of sense!

These videos are absolute gold. Thank you! The book is my next purchase.

Awesome! Thank you!

Great video as always. I like white wash and stucco. Matching right mortar to the type of masonry used. So it can wick moisture and dry out. Water logged masonry fails. Masonry loves to wick moisture. I like duck coat or rubberized coating at and below grade. I like stone going above splash line and then start soft masonry materials like brick that hold moisture and less resistant to natural acids in environments.

What about things like thorocoat/thoroseal? Is that an effective way to waterproof exterior bricks? I had that done but im mot sure how effective it is (especially since i think they only did one layer)

I'm a bid confused by the need to have the fluid applied waterproofing to be vapour open, whereas the dimple mat is closed. How much bulk water ever makes it past the parge coat once the building is structurally settled (no cracking) and exterior repointing with silane etc treatment added? Not a lot. A vapour open layer allows evaporation, which allows salts to be transported and concentrated near the surface. If it's closed, then there's no such effect. What percentage of the total amount of drying done by the wall with IWI, over the sensitive wet/cold months, will occur internally through vapour diffusion? Does that small percentage matter overall? How much heat loss should we allow, to promote external drying, to compensate for this lack of internal drying? I'm guessing it's not a lot. The mass wall is meant to be able to act as a hydric and thermal buffer. The outer mortar joints will start to fail once the silane treatment fails, salts accumulate and freeze thaw occurs, and you have a visual indication of when maintenance should begin, as well as access to the building. An internal method of drying these signs will be hidden, and inaccessible. I know there are types of plaster that are very tolerant to salt concentrations (European restoration plasters have pores large enough to allow salt formation until it's saturated, so spalling doesn't occur, although the salt concentration still attracts moisture). Something here doesn't sound right to me. I know this isn't a free building consultancy training service, so I'm not expecting a response.
